2. Cell (biology) - Wikipedia

   en.wikipedia.org/wiki/Cell_(biology)

   The cell is the basic structural and functional unit of all forms of life. Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function. The term comes from the Latin word cellula meaning 'small room'. Most cells are only visible under a microscope.

3. Structure–activity relationship - Wikipedia

   en.wikipedia.org/wiki/Structure–activity...

   The structure–activity relationship (SAR) is the relationship between the chemical structure of a molecule and its biological activity. This idea was first presented by Alexander Crum Brown and Thomas Richard Fraser at least as early as 1868. [1][2] The analysis of SAR enables the determination of the chemical group responsible for evoking a ...

4. Cell biology - Wikipedia

   en.wikipedia.org/wiki/Cell_biology

   e. Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. [1][2] All living organisms are made of cells. A cell is the basic unit of life that is responsible for the living and functioning of organisms. [3] Cell biology is the study of the structural and functional ...

5. Vesicle (biology and chemistry) - Wikipedia

   en.wikipedia.org/.../Vesicle_(biology_and_chemistry)

   Vesicle (biology and chemistry) Scheme of a liposome formed by phospholipids in an aqueous solution. In cell biology, a vesicle is a structure within or outside a cell, consisting of liquid or cytoplasm enclosed by a lipid bilayer. Vesicles form naturally during the processes of secretion (exocytosis), uptake (endocytosis), and the transport of ...

6. Cell theory - Wikipedia

   en.wikipedia.org/wiki/Cell_theory

   In biology, cell theory is a scientific theory first formulated in the mid-nineteenth century, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all living organisms and also the basic unit ...

7. Biochemistry - Wikipedia

   en.wikipedia.org/wiki/Biochemistry

   Biochemistry is the study of the chemical substances and vital processes occurring in live organisms. Biochemists focus heavily on the role, function, and structure of biomolecules. The study of the chemistry behind biological processes and the synthesis of biologically active molecules are applications of biochemistry.
